Re: Check Engine Light - Knows very little about cars
What mattmag said.
Assuming that the OP's VIN is before the production break, it also appears that the dealer is correct on the ECM replace/reflash. There is a TSB to address a P0420 + P0136 issue. If they also need the converter, I will assume that they have done a test to check the performance of the catalyst.
